L. RUBINSTEIN ELECTRIC IRON Filed Aug. 25, 1941- [lllz Patented Nov. 17,1942 UNITED lSTATES 2,302,476 i ELEcTB-rc moN Louis Rubinstein, NewYork, N. y. Application August 25, 1941,'seria1 No. 408,249 (o1. sii-77) i 1 Claim.

This invention relates to an electric iron, the object of the inventionbeing to provide the iron with 4automatic means for keeping the waterlevel in the tank of the iron constant and without necessitating thefrequent refilling of the tank by the operator.

' Another object of the invention is to provide means whereby the steamfrom the iron can be caused to pass through perforations in the bottomthereof to contact articles being pressed or to have the steam passthrough a hose or conduit to a remote point or to escape into theatmosphere.

This invention also consists in certain other features of constructionand in the combination and arrangement of the'several parts to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail,-reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts vthroughout the several views, and in which- Figure1 is an elevational view showing the parts of the invention associatedwith an iron.

Fig. 2 is a vertical sectional view through the iron.

Fig. 3 is a view in section through the water receptacle. n

Fig. 4 is a sectional view through the steam tube with the valve thereinin elevation.

In these views the iron is shown at A and it is provided with a tank I,which is heated by an electric coil. 2 in theusual or any desiredmanner, the connections from the coil to an electric supply being showngenerally at 3. A pipe 4 eX- tends into the tank I through a nipple 5 inthe upper part of the iron in one end thereof and this pipe isadjustably secured in the iron by the nuts 6 so that theA distance thelower end of the pipe is from the bottom of the tank can be adjusted toregulate the level of the water in the tank. A hose 1 is connected tothe outer end of the pipe in any suitable manner and said hose isconnected toa water container 8 by a cock 9 and said water container isprovided with a flllwill enter the container l through the hose I andthus the water willagain begin to flow into the tank until the waterlevel closes the lower end of the pipe. Thus the water level in the tankI is automatically maintained and there is no necessity for the user'tostop work and rell the tank', `as inl irons vas now constructed.

A vertically arranged tube I3 passesl through.

the iron and has its lower vend connected to a downwardly flaring"member Il fastened to the bottom of the iron and covering theperforations I5 formed in the bottom of the iron. The upper end fof thetube passes through the top of the iron and this end is closed by a capI8 and a branch tube I'I extends upwardly and outwardly from the upperportionof the tube I3. A valve I8, made in the form of a piston isslidably arranged in the upper portion of the tube I3 and has a stem I9connected therewith which through the cap and has a handle 20 at itsupper end. A pin 2l extends from the upper portion of the stem and isadapted to engage the bayonet slot 22 formed inthe cap for holding thevalve I 8 in lowered position. When in lowered position the valve I8will pass below a port 23 in the tube I3 and below the plane of the partI1, y

whereby steam will pass through the port 23 and passfthrough thev partII. A spring 25 normally holds the valve' in position closing the partI1 and opening the port 23. In this position of the partssteam will passthrough the port 2 3 ing nipple I0 in its top closed by a cap II in afluid tight manner.

Of course the water container must be held in an elevated position sothe water therefrom will pass through the hose 1, when the cock 9 isopen, through the pipe 4 to the tank I. When the water level in the tankcloses the lower end of the pipe the flow of water will be stopped aso1' course no air can enter the container. However,"

as soon as the water level in the tank drops air 66 and. ow 'downwardlythrough the pipe I3 and pass throughtheperforations I5 in the bottom ofthe iron and contact articles being ironed.

When it is not desired to use the steam, the

valve Is lowered and held in lowered position by the pin 2| engaging4the bayonet slot 22 and the steam will pass-through the port 23 andescape through the part I1. f If desired a hose can. be connected tothisjpart I1 for leading Vthe steam to a distant point or for use insteaming an article or object. Y

Thus it will be seen that I have provided means for automaticallymaintaining the water in the tank I of the iron at a constant levelwhich removes the-necessity of the user frequently relling the tank,with means for supplying the steam to the article being ironed andcutting oif the fsteam supply to the article whenever desired.

Itis thought from the foregoing ldescription invention will be readilyapparent.

that the advantages and novel'features of theV It is to be understoodthat changes may be made in the construction and'- in the combinationand arrangement of the several partsprvided jacent the top of the sameand being provided with a forwardly and upwardly inclined vent branchabove said port extending out of said top,

a downwardly aring member on the bottom of the tube fitting against saidbottom and spanning said group of apertures, a plunger-type springtensioned valve in the upper end of the tube normally closing saidbranch and opening said port .and slidable into a downward limit ofmovement to open the branch and close the port, said valve having anupstanding stem extending out of the top o! the tube for moving thevalve under nger pressure exerted on the stem, and

cooperating devices on said stem and in said tube, respectively, forlocking the stem and valve down in said limit of movement thereof.
